14. 3 March 2004 OST ETOPS/LROPS presentation14 Main differences with FAA NPRM Type designType design IFSD rate objective for twins over 180 mn diversion time (historical difference) JAA: decreasing curve down to 1x10 -5 /FH ( 25.1309 objective) FAA: flat curve at 1x10 -5 /FH Icing capability Fuel feeding in emergency electrical conditions

15. 3 March 2004 OST ETOPS/LROPS presentation15 Main differences with FAA NPRM Operations Operations - FAA and JAA are consistent on two engines aeroplanes and 3-4 engines aeroplanes above 180 mn diversion time - Differences on polar designated areas on polar designated areas intermediate FAA step at 240 mn diversion time intermediate FAA step at 240 mn diversion time - Recovery plan required by ARAC on all alternate airfields.

16. 3 March 2004 OST ETOPS/LROPS presentation16 Main differences with FAA NPRM ETOPS vs LROPSETOPS vs LROPS FAA NPRM refers to ETOPS for all operations requiring planned en- route alternates due to similarities in the OPS requirement FAA NPRM refers to ETOPS for all operations requiring planned en- route alternates due to similarities in the OPS requirement JAA refer to ETOPS for twins and LROPS for 3 and 4 engines aeroplanes due to differences in threshold, flight operations and design considerations. JAA refer to ETOPS for twins and LROPS for 3 and 4 engines aeroplanes due to differences in threshold, flight operations and design considerations.

17. 3 March 2004 OST ETOPS/LROPS presentation17 Response to AEA concerns Do not jeopardise existing operations Do not jeopardise existing operations Analysis of the 2 examples given: Anchorage to Tokyo is not an LROPS route (JAA criteria). LAX to Tahiti could be marginally LROPS (see also fuel requirements)  LROPS rules do not affect existing operations Grand father rules. 3 and 4 engines aeroplanes from an existing Type Certificate are eligible for LROPS. However CPR certification rules apply to significant changes. Grand father rules. 3 and 4 engines aeroplanes from an existing Type Certificate are eligible for LROPS. However CPR certification rules apply to significant changes. No JAA polar designated areas would apply to existing polar routes No JAA polar designated areas would apply to existing polar routes
